When I replace the existing height which is calculated using calc() with height:auto, a white space at the bottom appears when viewed in mobile devices. Is there any alternative to height:auto to be used in the code. I tried using vh instead of %, using overflow property, but it didn't work ?

These two are the problem

html {height: 100%;}
body {height: 100%;}

100% height of html and body is a heigh of a viewport, and not a whole document. Inner elements made the common height more then viewport and it could make the whitspases you are taking about.

Remove your custom script at all. I will write down only CSS classes, i made changes in. Replace and it will work.

html {
  height: 100%;
  margin: 0;
  padding: 0;
}
body {
  position: relative;
  min-height: 100%;
  margin: 0;
  padding: 0;
  background-color: #111111;
}
nav.bg-dark {
    background-color: var(--main-bg1-color) !important;
    height: 53px !important;
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    z-index: 2;
}
.bg {
    min-height: 100vh;
    padding: 53px 0 60px 0;
    box-sizing: border-box;
    width: 100%;
    background-color: var(--main-bg2-color);
    display: flex;
    justify-content: center;
    align-items: center;
    z-index: 1;
    position: relative;
}
.footer {
    background-color: #111111;
    height: 64px;
    display: flex;
    align-items: center;
    position: absolute;
    bottom: 0;
    right: 0;
    left: 0;
    z-index: 2;
}
@media (min-width: 576px) and (max-width: 767px) {
  .bg {
    padding: 53px 0 156px 0;
  }
}

Remove height attribute from each .bg in the css portion (I counted 3 total). Also remove min-height: 507px; from both .outer-box in css.

Change your html and body css to read as follows. This will ensure your elements are encompassed by your body tag, and body by html tag:

html,body{
  margin: 0;
  padding: 0;
}

I tried your code with the modifications I mentioned, with and without your JS, and it didn't seem to make a difference. It doesn't seem like your JS is really required if you use the modification to css and are wanting to remove the white space at bottom of your page. See JSFiddle https://jsfiddle.net/s97htk0p/

Your modified CSS code:

html,body{

  margin: 0;
  padding: 0;
}
